general problems

Hello,

we have the following problems:

1//
How can we give the “add to cart” button a different colour on the up-sell?

2//
How can we make the “add to cart” button in the up-sell wider?

3//
Why doesn’t the price change when I select a different and more expensive size in the up-sell? It always says from 17$ and does not change the price according to the selection.

4//
How can I remove the Button “Continue Shopping” in the up-sell?

Thank you
